Frequently asked questions

How do I resize an image without losing quality?

Making an image smaller keeps it sharp. Making it larger cannot add real detail, so enlarge only slightly. Keep the aspect ratio locked to avoid distortion.

What is the difference between resizing and compressing?

Resizing changes the pixel dimensions. Compressing changes how the pixels are stored to reduce file size. Smaller dimensions also reduce file size.

Can I resize many images at once?

Yes. Add several files and the same settings are applied to each one, then download them as a ZIP.

Are my images uploaded to a server?

No. PixTools processes images locally in your browser using your device. Your files are not uploaded or stored.
